STORE-SERVICE APPARATUS.

SPECIFICATION forming part of Letters Patent No. 371,962, dated October25, 1887.

Application filed May 3, 1887. Serial No. 236,927. (No model.)

.To all whom it may concern.-

Be it known that we, ROBERT A. lVICOARTY and HENRY You, citizens of theUnited States, residing at Detroit, in the county of Wayne and State ofMichigan, have invented a new and useful Improvement in Store-ServiceApparatus, of which the following is a specification.

The drawings represent, in Figure 1, a side view of the mechanismemployed in our invention, and in Fig. 2 a plan view thereof, thecarrier being disconnected from the catch.

A wire way or track, WV, is stretched between two points and passes overor near to the stations between which it is desired that the carrier Ashall travel. At each of the stations we clamp upon the wire ablock, B.This block supports in a position beneath the wire a pulley, P, and acatch, C, which is hung upon trunnions at O and has abell-crank hairdle, H, projecting upward above the wire. The hook part L of the catch Clies under the wire NV and closely adjacent thereto, and is held up inposition by the light spiral spring S. To 2 the upper part of the handlepart of the catch C we attach an arm, R, which is held to the handle Hby a pin passing through the slotted opening P in the upper end of thehandle H. This arm It slotted at its lower end, so as to engage and rideupon the wire \V, and also at its lower end is perforated to permit thepas sage of the cord K.

Upon the wire XV we mount two sliding blocks, M and N, one on eitherside of the catch holding mechanism, previously described. These blocksare perforated to permit them to move freely upon the wire 7, and theperforations are in vertical diameter considerably greater than thediameter of the wire W, so that a considerable vertical movement ispossible, but little or no side movement can be had. The two blocks Mand N are connected by the spring-wire V. The spring-wire V has one ormore coils made at its middle 5 part to give it an increased resiliency,and has one end firmly fixed to the block N and the other end attachedto the fork X, which passes up at the sides of the catch C to the blockM, and is there attached to the block M by a pin or hinged joint, J. Theblock M has two prongs, Y, extending upward from its lower side, betweenwhich lies the catch C when the spring is in the position shown in thedrawlugs.

0 the block N We attach the cord K, which passes forward over the pulleyP and downward to a position to be reached by the hand of the operator,and ends with a handle,

T, by which it may be grasped. The end of the car A is provided with alooped wire or 6 with an opening adapted to pass over the hook Lofthecatch C.

The operation of the mechanism is as follows: The loop upon the car isbrought into engagement with the hook L,and when brought 6 into thatposition has necessarily pushed the, sliding block M before it, so thatthe sliding block M will lie between the block B and the rear end of theear. The prongs Y of the block will then lie on either side of the catchC and below the end of the car A. The block N will. be thrown by thespreading force of the spring V to the extreme limit of its mo tion backof the block B.. The operator now grasps the handle T of the cord K andpulls downward, bringing the block N forward and putting tension uponthe spring V. The downward pull is continued until the button Z upon thecord K is brought into contact with the lower end of the arm Thespreading force of the spring causes the block M first to press forwardagainst the rear of the car, which is held from forward motion by thehook L, and next to press upward slightly by means of the prongs Y, thuspreventing the loop on the car from following the hook L when the hookshall be drawn downward by the next movement.

A continuation of the downward pull. upon the handle T now pulls the armR forward to a position parallel to the position that it first 0 held,and pulls the arm II forward and the catch C downward until the hook Lisout of engagement with the loop on the end of the car. The instantthis'engagement ceases the spring V expands, and the block M is thrown 5forward, pushing the car in front of it with a sudden impulse sufficientto propel the car along the way, the distance and velocity of coursedepending on the strength of the spring V and the amount of compressionthat has been given to it.

Having thus described our invention and its mode of operation, what weclaim as novel, and desire to have secured by Letters Patent, 1s

1. In a store-service apparatus, the combination of a catch hinged to ablock arranged to be clamped upon a wire way, two movable blocks adaptedto slide on said Way, and a spring connecting the two blocks together.

2. The combination of a hooked catch, a spring propelling mechanisminterposed between slides mounted on awire way, and a lever connectedwith said catch by which the catch is moved from its normal position.

3. The combination of a catch hinged to a block mounted upon a wire way,a block sliding upon said wire way, a spring connecting said block to asecond block, and a cord pass-- ing from the second block over a pulley,by means of which the spring is placed in a state of tension,substantially as described.

4. In a store-service apparatus, the combination, with a car, of aspring mechanism for propelling'the car, both ends of which spring areattached to blocks sliding upon the wire of the main track.

5. In a store-service apparatus, the combination, with a car, of aspring propelling mechanism, both ends of which spring are free to movethrough a limited space, and a pronged block attached to one end of thesaid spring and sliding upon the wire of the track, the prongs of whichblock pass down on either side of a catch mounted on the wire betweenthe ends of the spring.

6. In a store-service apparatus, the combination of a car adapted totravel on a wire way, a wire way having mounted thereon a catch adaptedto hold said car, a sp ring-motor, both ends of which are movable alongthe wire track, one end of which is adapted to push against the said carwhile the car is held by the catch, and the other end of which isadapted to be pulled toward the firstdescribed end until tension isproduced in the said spring snfficient to propel the car along the way.

7. The combination of a way, a car adapted to travel thereon, a pivotedcatch mounted fixedly on the way, blocks sliding on the way and pressedapart by a spring, a cord for drawing the blocks together andcompressing the spring, and an arm connected to the catch and to thecord for rocking the catch to release the car, substantially asdescribed.

8. The combination of a way, a car adapted to travel thereon, a pivotedcatch mounted fixedly on the way, blocks sliding on the way and pressedapart by a spring, one of which blocks being provided with an extendedend adapted to lie upon the side of the catch, a cord for drawing theblocks together and compressing the spring, and an arm connected to thecatch and to the cord for rocking the catch to release the car,substantially as described.
